Tip- Off On Buying Acetone. Don't Buy In Paint Sections.

What size bottle? I get quarts from the wife's hardware store for $2.00. , But then again that is my price which is cost.

I bought a quart at Home Depot for $4.49 a couple of months ago. Didn't really do any price checking.

Found mine at Walgreen's; don't remember how much. Makes a great paintbrush cleaner, too.

I use "Onyx" brand too. No complaints!

I paid $5 for a quart, but I need it to clean my brush when I restain my deck.

Now you tell me

ODD. I've tried Walmart, Kmart, Target, Walgreens and so far have never found pure Acetone in anyplace except the Paint sections. In the Jewlery sections all I see is Acetone mixed with almost anything ever made. And there is a reason for that. Normally 100% Acetone is punchent, dangerous and the fumes somewhat dangerous and Women know that. Many contain perfumes and additives to soften nails also and Women know that also.
I'll go today and check again but I suspect there is some small print on the bottle somewhere. And as to cost. Never found it by the quart for more than $4.50. And just what is wrong with a quart? Remember it's in the paint department, not in the coin collecting department. Just have some paint purposes don't you think?

Regardless of what the label says or where you purchase it from(unless you have access to ACS reagent grade acetone which you probably do not), you should always perform an evaporation test to check the purity. Pour a small amount in a clear glass plate or bowl. The acetone should evaporate fairly quickly at room temp, leaving no residue behind. If there is some liquid that does not evaporate or there is a haze left on the glass, that acetone is not pure enough to use on a coin.
